1338362-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338362-92-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,6 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1338362-92:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*6)+(3*2)+(2*9)+(1*2)=167
167 % 10 = 7
So 1338362-92-7 is a valid CAS Registry Number.

Synthesis of 2 H-indazoles by the [3 + 2] dipolar cycloaddition of sydnones with arynes
Fang, Yuesi,Wu, Chunrui,Larock, Richard C.,Shi, Feng
, p. 8840 - 8851 (2012/01/02)
A rapid and efficient synthesis of 2H-indazoles has been developed using a [3 + 2] dipolar cycloaddition of sydnones and arynes. A series of 2H-indazoles have been prepared in good to excellent yields using this protocol, and subsequent Pd-catalyzed coupl
